extracts
'This could be the best snowfall to hit the Stirling Ranges in recent years with snow expected to fall as low as 600 metres, potentially covering not only Bluff Knoll but also the nearby Porongurup Ranges.

Icy blast on its way

So far this year, snow records have already been broken with the earliest recorded falls occurring on April 19.
....
Widespread falls expected

At 1,099 metres above sea level, Bluff Knoll usually sees a handful of snow events during the winter months but it is rare for the forecast to predict falls on lower peaks of the Porongurups, such as the 670-metre Devils Slide.
